PM Fiber Isolator
The 1310nm 1480nm 1550nm PM Fiber Isolator from Optico is a high performance Passive optical device designed for PM Fiber systems that require high stability, low loss and high isolation. The isolator uses the non-reciprocal Faraday rotation effect to effectively isolate reflected and excess light reflux, thereby protecting the light source equipment and ensuring the directionality of signal transmission.
Optico's PM fiber isolator is particularly suitable for high-precision fiber applications that require optical signal polarization preservation to ensure stability in slow-axis transmission. At the same time, the device supports a variety of header types, with flexible customization capabilities to meet the needs of a variety of application scenarios.
The Polarization Maintaining Isolator 1310nm 1480nm 1550nm is used to keep light travel in only one direction while blocking the light traveling in the opposite direction. It can operate at the range of wavelengths 1310nm, 1480nm, and 1550nm of light.
OPTICO offers a range of high-quality polarization maintaining isolators designed for use in various optical systems. With its exceptional features, the Polarization Maintaining Isolator 1310nm 1480nm 1550nm is an ideal choice for telecommunications, aerospace, and defense applications where maintaining polarization is critical for optimal performance.
